Preheat oven to 350. Spray a 2 quart casserole with cooking spray and set aside. Dice bacon and fry until crisp. Remove with a slotted spoon, leaving drippings in pan. Add butter, nutmeg and onions. Saute onions over low heat until nicely browned. Add the bacon back in. In a microwave safe cup, melt butter and then add cream and cheese. Stir to melt, heating for 20 second intervals as needed. Place 1/2 the turnips in the bottom of the casserole then salt and pepper, followed by 1/2 the onion mix and 1/2 the cheese sauce. Repeat layers then top with additional cheese if using. Cover well and bake for 30 minutes. Uncover and bake 15-20 minutes or until top browns and it's all bubbly and tender.

Made this for dinner tonight along with marinaded grilled pork chops and they were AMAZING. I used a combination of smoked gouda, smoked swiss, and parmesan. Totally amazing recipe and you could not tell the turnips were not potatoes. Worthy of any holiday meal.
